Sample Terminate but Stay Resident assembly program.
TSR.ASM is the source code used to create TSR.EXE
TSR.EXE really does nothing... it is just an example.
It replaces interrupt 0 with a new interrupt vector
pointing to code which makes a far_jump to where interrupt
0 used to point. I use tsr.asm as a skeleton when writing
other TSR programs (to grab the keyboard, printer, screen,
disk, etc. interrupts). It needs DOS 2 or higher.
If you improve it, send me a copy...
